Looking for advice rpg singleplayer/multiplayer

Yeah, for sure going to aim for a protype with horrible graphics, i have no hurry and it’s mainly to learn. I have been working with unity for one year and recently changed to unreal, loving it so far.

i guess the best way to describe what i want would be something like torchlight, diablo, etc. Where you can play alone or join a 4 friends squad to grind.

i think i’m going with single player and then updating it later if needed and if it gets too hard, just re-do it. In the end, the purpose of this is to learn and have fun doing the game.
